Abstract (en)
[origin: EP1517004A1] The wheel (1) has a turbine disk (4) comprising an upstream flange (14a) and a downstream flange (14b), both extending around a main longitudinal axis (2). One of the flanges is conceived in an elastic manner such that the flanges pass from spaced apart position to assembled position and vice-versa, respectively by exerting pressure on the flanges and by releasing the exerted pressure. An independent claim is also included for a method for assembling a turbine wheel.
